When I first started online many years ago, having never played Texas
Hold 'em before, I played just about every hand. It took me awhile to realize that I was throwing away a lot of chips on hands like 7-4, J-6, etc. You will eventually have to figure out what is your comfort level, and you'll have to learn things like position (an A-6 is not as strong early as it is late when everyone has folded to you), how to avoid chasing flushes, straights or sets, etc. Practice is the best teacher. Good luck, don't play with more than you can afford to lose, and have fun.
